Iodised salt contains a very small amount of iodine added to prevent iodine deficiency. When heated during cooking, the iodine content in iodised salt does not vaporize or sublimate significantly to create a health concern. Hence, the amount of iodine present in the food after cooking from iodised salt is negligible and safe.
KFC use fine iodised sodium chloride.
It is iodised so it flows easier and does not stick in clumps
Any difference exist. The correct term is "iodised"; also I suppose that you think to dissolution not to melting.
